Support for Parameter Types in Scenario Outline

[tillkrischermaterna]

🤔 What's the problem you're trying to solve?

I want to be able to go to definition from the Given today is <day> line in the following setup:

friday.feature

Feature: Is it Friday yet?
  Everybody wants to know when it's Friday

  Scenario Outline: Today is or is not Friday
    Given today is <day>
    When I ask whether it's Friday yet
    Then I should be told "<answer>"

    Examples:
      | day            | answer |
      | Friday         | TGIF   |
      | Sunday         | Nope   |

steps.js

import { strictEqual } from 'assert'
import { Given, When, Then, defineParameterType } from '@cucumber/cucumber';

defineParameterType({
  regexp: /Monday|Tuesday|Wednesday|Thursday|Friday|Saturday|Sunday/,
  name: 'day',
  transformer: s => s
})

function isItFriday(today) {
  if (today === "Friday") {
    return "TGIF";
  } else {
    return "Nope";
  }
}

Given('today is {day}', function(givenDay) {
  this.today = givenDay;
});

When('I ask whether it\'s Friday yet', function() {
  this.actualAnswer = isItFriday(this.today);
});

Then('I should be told {string}', function(expectedAnswer) {
  strictEqual(this.actualAnswer, expectedAnswer);
});

✨ What's your proposed solution?

Plug in the values of the first scenario into the step and match using that.
